Stability/Exercise Sitzball Alba MHBALL K — seating diameter 650 mm, PVC inner ball, polyester cover, khaki

Alba MHBALL K is a stability and exercise sit ball with a seating diameter of 650 mm, constructed from a durable PVC inner ball and finished with a polyester cover in khaki. Designed to support ergonomic seating and a range of fitness and rehabilitation exercises, this single-piece ball is suitable for use at home, in studios or in offices as an active alternative to a conventional chair. The 650 mm diameter suits taller users or setups where a higher seat height is required.

Advantages

The PVC inner ball provides reliable air retention and resistance to everyday wear, while the polyester cover offers a comfortable non-slip surface and a neat appearance in khaki. Using the Alba MHBALL K encourages micro-movements that help improve posture and engage core muscles during sitting or exercise. The single-piece design makes it simple to set up and maintain without additional assembly.

Suitable for

• Ergonomic active seating in home or office environments
• Core strengthening and balance exercises
• Light rehabilitation and physiotherapy movements
• Fitness studios and group classes using stability balls

This ball is intended for typical home, studio or office use and may not be suitable for very heavy-duty commercial applications or environments requiring medical-grade certifications. Users who require a specific anti-burst rating or custom inflation characteristics for clinical procedures should verify compatibility with professional requirements before purchase.

How to use

Inflate the PVC inner ball to the recommended firmness for a 650 mm ball, then fit the polyester cover if supplied as a slip-on. Use the ball as an active seat by placing it on a flat, stable surface and adjusting posture so hips are slightly higher than knees for ergonomic alignment.

Follow any additional physiotherapy guidance if using for rehabilitation.

What to consider before purchase

• Confirm 650 mm seating diameter is appropriate for your height and desk/chair setup
• Check inflation tools and surface requirements for safe use
• Assess whether a polyester-covered ball meets your comfort and cleanliness preferences

Usage recommendations

Place the Alba MHBALL K on a non-slip mat for added stability during seated work or dynamic exercises; inspect the ball periodically for signs of wear and maintain recommended inflation to preserve ergonomic benefits and safety.
